Configured for analog signal routing and module termination in Bailey Infi 90 platforms, the ABB NKAS01-9 (NKAS01-9 Analog Module Termination Cable) provides direct physical/electrical execution. It interconnects front-end analog I/O units to MMU-TU termination assemblies over a 9 ft (2.74 m) path. The cable incorporates 20-22 AWG multi-conductor wiring rated for 300 V AC and 2 A per conductor across operational thermal environments spanning -20 deg C to +80 deg C.

Cable Identification & Part Breakdown

• NKAS01-9: Complete assembly part number specifying a 9 ft total cable length.

• MMU-TU Interface: Dedicated connector termination profile mating module slots to terminal units.

Hardware Specifications

Deterministic IO Signal Integrity & Backplane Integration

The NKAS01-9 assembly enforces precise signal fidelity across expanded Infi 90 chassis structures, preventing high-frequency noise insertion into low-level analog channels. Optimized conductor spacing maintains high backplane bus communication velocity and protects differential analog inputs from adjacent field interference. Cable shielding and low-impedance paths support high I/O density scaling while maintaining full firmware flash compatibility and signal alignment across host controller racks.

Field Installation Guidelines

• Cable Routing Limits: Route the termination cable through dedicated low-voltage wiring troughs separate from high-voltage AC power lines.
• Bend Radius Compliance: Maintain a minimum static bend radius of 6x the overall cable diameter during cabinet installation to prevent conductor fatigue.
• Connector Latching: Engage both strain-relief retention screws fully at the MMU-TU interface to prevent accidental mechanical disconnects.
• Shield Grounding: Ensure the integrated overall shield ground braid connects directly to the cabinet frame ground bar to optimize noise suppression.

Frequently Asked Questions

• What is the maximum current capacity per conductor on the NKAS01-9?

  Each conductor inside the assembly supports a maximum continuous current rating of 2 A.

• What system interface does the NKAS01-9 termination cable connect?

  It connects Bailey Infi 90 analog modules directly to MMU-TU field termination units.

• Is the cable rated for operation in high-temperature environments?

  Yes, the assembly operates continuously within an ambient temperature range of -20 deg C to +80 deg C.

• What conductor wire gauge is utilized inside the cable assembly?

  The cable uses multi-strand copper conductors sized between 20 AWG and 22 AWG.

• What dielectric voltage rating applies to the NKAS01-9 assembly?

  The internal conductor insulation carries an official electrical insulation rating of 300 V AC.

• How should the overall cable shield be grounded during field setup?

  Connect the shield drain wire to the dedicated chassis ground lug at the termination unit end.

• Can the NKAS01-9 cable be hot-plugged during active process execution?

  Disconnect analog loop power before unplugging the cable to prevent signal disruption to active loops.

• What measures prevent signal cross-talk across adjacent analog channels?

  Individually twisted conductor pairs with overall foil and braid shielding suppress channel cross-talk.
